(Cl. Z50-33) 16 Claims.

This invention relates to radio antennas, and has particular reference to extensible and retractable antennas which may be used on automobiles or other vehicles.

The primary object of the present invention is to provide an antenna which may be operated, by a single control within the vehicle, either to swing the antenna up or down about its mounting on the vehicle body, or vary its extension above the body.

A more particular object of the invention resides in the provision of an antenna which may, for example, be brought from fully extended to fully retracted position, and thereafter may be caused to swing downwardly about its mounting, all by the continuous movement, in one sense only, of a single control within the Vehicle. Preferably the antenna is mounted on an automobile roof directly above and near the center line of the windshield.

Afurther object of the invention is to provide an antenna comprising-two or more intertting or telescopic sections, in which the upper sections may be adjusted as to extension, to suit varying conditions of signal reception; and in which', at the will of the operator, the upper sections may be substantially or completely telescoped within the lower section, after which the antenna may be swung about its pivot point and disposed adjacent the windshield mullion.

The invention also contemplates and has as a further object the provision of a exible joint in the mounting head, to permit the antenna to fold forward or backward in the event that it is accidently struck while extended, as in passing.

under a low garage door.

Still another object of the invention is to provide an antenna, the various parts of which will 'make Agoed electrical connection, even after long periods of use.

A further object of the invention is to provide an antenna which may be sold as a complete, operative unit, and may be installed Without the necessity of disturbing or adjusting theworking parts.

Other objects and advantages of the invention will be best understood by a consideration of the following description taken together with the accompanying drawings, wherein is illustrated a preferred embodiment of the invention.

Referring more particularly to the drawings,

Fig. 1 shows the device mounted on an automo-f bile roof, generally indicated at 2, just above the center mullicn 3 of the windshield fi. .The mech.- anism is illustrated in the fully retracted restposition, i. e., with the antenna basel section 5 swung downwardly and in snap-engagement with a support member 6 xed to the mullion 3. As appears in the ligure, the stanchion tube 8 is held in the inside and outside roof members 9 and I0, by means of collar and nut assembly I I, and outside collar I2. To prevent rotation of the stanchion tube, it may be keyed to member I2.

The collar members are made of insulating material so as to insulate the antenna from the automobile body, and a lead-in rod I3 is provided. This rod may be connected to any convenient part of the antenna assembly, as by means of clip I3a, since the two collar members effectively insure that the entire assembly is insulated fro-m the car body. In this connection, it should also be noted that the construction of the entire antenna is one which assures good electrical contact, from the extensible antenna section, back through the device to the lead-in wire. As will appear fully hereafter, the extensible section is moved by means of a driving tape, one end of which is xed to said section and the other to a reel nested within the head. Since this tape is spot welded to the extensible section, it may be seen that the construction, in effect, provides a continuous lead-in wire extending throughout the device.

Control knob I 4 is provided within the car and, as will be brought out fully as the description proceeds, the mechanism is such that clockwise rotation of this knob will rst swing the antenna up to the position shown in Fig. 2, and secondly extend an additional antenna portion I5, as may be vseen in Fig. 3. Rotation of knob I4 in the counter-clockwise sense, will first cause portion I 5 to be telescoped within the lower section 5, and continued counter-clockwise rotation will serve to swing the antenna downwardly to the rest position shown in Fig. 1. It should be here pointed out that the control requires simple rotational movement only, and that the mechanism conditions itself so as to initiate extension and swinging movements of the antenna in their proper sequence.

The individual parts by which the advantages of the mechanism are realized, will now be taken up in detail. Y f

Figs. 6 and 6A show that the xed, stanchion tube 8 has an enlarged cap portion I6 having an annular ange II extending rearwardly therefrom. Apertures I8 and I9 are formed in the cap portion I6, for a purpose which will appear later. The tube 8, shown broken away for convenience, is hollow to accommodate the driving shaft, and as appears in Figs. 1, 4 and 5, has an externally threaded portion 20, adapted toI cooperate with the mounting nut.

Disposed within the annular flange Il and concentric therewith is an annular shoulder portion 2l in which is countersunk a bore 22, of larger diameter than the bore in the tube 8, and having anarcuate stop shoulder 23 formed therein (see Fig. 1 6).

` Behind the cap portion I 5 are two pairs of short projecting ypins 24-24, as most clearly appears in Fig. 16. VA pair of arcuate spring members Y25 and 25 (Fig. 7), having forwardly proliecting-portions 21 and 28, are arranged behind the cap portion I6 with portions 21 and 28 disposed in openings I8 and I9, and the springs are securely fastened to the pins 24 as, for example, by riveting. The springing action of these arcuate `members is such that portions 21 and 28 tend to resist alforce acting to move them out of apertures I8 and I9. As clearly appears in Fig. 16,

portion 28 is substantially wider than portion 21 and thereby extends radially outwardly further than portion 27. To assure positioning the proper spring in its corresponding aperture, only one of the apertures, i. e. aperture I9, is made wide enough to accommodate the wider portion 28.

Referring now to Figs. 8, 17 and'17A, the head portion 1 is adapted to be rotatively carried by the stanchion member just described. The back of this centrally-bored head member (Figs. 3 and 17A) is configured to cooperate with the face of the stanchion member, and has two projecting legs 29 and 38, of arcuate outside shape, which `are adapted to seat in the counterbore 22 o-f the stanchion member, and provide a bearing for rotation of said head with respect to the stanchion. Leg 29 is providedwith a projecting portion 3|, which, when the two members are fitted together, extends sufficiently far into the counterbore 22 to engage the stop-shoulder 28 formed in said counterbore. This stop-shoulder and the cooperating portion 3I are so formed as to permit only 180 rotation of the head with respect to the stanchion. At either end of this travel, as may be seen by inspection of Figs. 16 and 17A, the portion 3i will strike the stop-shoulder 23. As appears from Figs. 8 and 17A, an aperture 82 is provided through the end wall 33 of the head, adjacent leg 29. This aperture is so positioned that when the head is at either end of its 180 travel relative to the stanchion, one or the other of the spring portions 2l and 28 will extend therethrough. Diametrically opposite to the aperture 32 there is provided a depression 34 into which will snap the spring which is not extending into said aperture.

. Referring to Figs. 17 and.19, the face of the head member 'l is bored out to a `depth suflicient to receive the real 35. Associated With a smaller bore which extends completely through wall 33, are two keyways 35 which, as best seen in Fig. 17A, extend partially through the legs 29 and 30. A further out 3'! is made partially through the wall 33. This cut begins at aperture 32 and extends through a circular arc of about Into this cut is fitted a reel locking bar 4l which is pivoted for limited rocking movement as at 42 and urged out of the recess 3l, at one end thereof, by a spring indicated in dottedflines at 43.

` This reel locking bar has oppositely turned lugs 44 and 45 at its ends (Figs. 9A, 17 and 17A) Lug 44 normally extends into aperture 32 formed in head 1, while lug 45 is urged outwardly from recess 8l by spring 43, toward engagement with radial slots 46 (Fig. 18A) formed in the back of reel 35.

- Head member "l is also provided at one side with a hollowed out shank 38 which,-as seen in Fig. 19, terminates in a conical portion 39, centrally bored at 40 to receive the lower antenna section 5.

Referring to Figs. 9, 9A, 18 and 18A, the reel 35 is provided at one side with a hub portion 4'! (see Fig. 9A), forming a circular bearing 4of a size to fit and turn freely within the smaller central bore of head member l. This hub 41 has a bored-out portion in which a pin 48 is fixed (Fig. 18A). Through this pin 48 the torque of drive-shaft 49 is transmitted to the reel, as by means of slot 58 formed in the end of said shaft (see Fig. 10).

The reel itself has an inner drum 5I (Figs. 9 and 18) upon which the drive tape 52, secured as at 53, may be wound. The reel is also provided with a circumferential Wall 54. The tape bears against this wall, and is guided thereby, during the unreeling operation, as described hereinafter. The tape 52 is preferably a steel tape of generally known form.

The cap member 55 is best illustrated in Figs. 14 and 15. This member has a central recessed bearing portion 56 to cooperate with a bearing spindle l formed on the front face of reel 35 (Fig. 18). A wall 58 on the cap member exactly fits and cooperates with the circumferential wall 54 of the reel. This wail 58 is of substantial depth at the lower portion of the cap, as viewed in Fig. 14, and of a very small depth at the upper portion of the cap. Thus, when the members are assembled, as seen in Fig. 4, the plane of the reel is cocked somewhat with respect to the passage in conical portion 39 of head member i. This permits the drive tape to unwind freely from drum 5| and to pass through gate 59 (see Fig. provided in wall 58, without interference by the reel wall 5.

The particular configuration of the reel and the cooperating head cap, is of importance as it enables the tape to be wound both in and out by the rotation of one barrel member. The cooperation between the drum 5l, wall 54 and cap- Wall 58, in the present device, provide both inner and outer winding reels. In operation, when the tape is wound in, the drum 5I serves as the winding drum, and when the tape is thrust out, walls 54 and 58 cooperate to form a tape extruding drum.

The inner and outer telescopic sections of the antenna, as well as the drive tape which is fastened to the above-described reel and drives said inner section, will now be more particularly described. Reference should be had to Figs. 5, 12 and 13.

The larger section 5 is cut away near its lower end, as at 69, and this end is snugly fitted into the hollowed shank 38 of the head. Cooperating cap member 55 is recessed as at 5|, which most clearly appears in Fig. 15. When section 5 is iitted into the head member, its lowermost circular portion seats in recess 6I of the cap member. A retaining screw B2 fastens the head and cap together, and it can be seen that lower section 5 is tightly held against endwise displacement in said head member. As appears in Fig. 13, the extensible tube I5 is iiatted as its inner end, and one end of the drive tape 52 is fastenedto this atted portion. To the opposite side of said portion is fastened a short tape section 53, which is employed to prevent rattling of the tube l5 within tube 5. As may be seen from the phantom lines on Fig. 15, as well as from the section of the reel illustrated in Fig. 1'?, the tape is brought in through hollow shank 38 of the head member, through aperture 59 provided in wall 58 of the cap member, fixed to the reel as at 53 and is then wound thereon.

Referring to Figs. 10 and 11, the former shows the driving shaft 49, while the latter figure shows a hollow tube 64 of a diameter to fit within the stanchion tube 8 and adapted to receive the driving shaft. one end thereof and is provided with two oppositely disposed and outwardly extending ears 85. Drive-shaft 49 has its corresponding end slotted as at 50. As assembled (see e) the tube and drive-shaft have operatively interposed between them a spring S8. This spring, by reacting between the annular wall 51 of the tube and a retaining washer 68, fixed to the driveshaft, maintains the two members in the relative axial positions shown in Fig. 4, under all normal conditions of operation of the device. However, the spring will permit tube $4 some axial movement with respect to drive-shaft 49. The direction and approximate extent of this movement,

will be apparent by a comparison of Figs. 4 and 5.

In assembling the device, referring to Figs. 4 and 19, the above-described drive-shaft and tube assembly is first inserted through the central bore of the head member 1, and the tube ears 65 engaged with the retaining keyways 36 formed in the head member. Following this, the stanchion tube 8 may be slipped onto tube Sii, and this assembly fastened against axial displacement of the parts, by a retaining washer 68a which clips into a circumferential groove formed adjacent the splined end 69 of the driveshaft. Next, the reel lock 4|, may be properly positioned, and the reel placed in the'recessed head with its drive-bar i48 in-v engagement with the slotted end of the` drive-shaft. Lastly,V the driving tape may be introduced and fastened to the reel, as above described. Positioning. the cap member 55 and inserting retaining screw 62 completesthe assembly. Positioning ofthe collars ii, and i2 as well as the inside finish bezel 'fil and control knob i4 has not been particularly described, as they are not a part of the antenna assembly per se,and may be utilized in any convenientorder when the antenna is being installed. v f

The operation of the device is as follows, and is described, with particular reference to Figs. 4:, 5 and 19. For purposes of illustration, it will be first assumed that the antenna is in the position shown in Fig. 1, and that it is desired to rotate it upwardly and extend it to the position shown in Fig. 3.

At this lower limit of the 180 rotation possibie between the head 'l and the fixed stanchion tube 8, the narrow spring lug 2T is protruding through the aperture 32 in the head. This spring lug being narrow, will not strike lug 44 of reel lockbar 4l, and therefore the forwardly extending lug l5 aty the opposite end of lock bar 4I will have moved on pivot 42 under the inuence of spring 43, into engagement with one of the radial slots it in reel 35. Since the lock bar 4I is fixed in the head member 1, the head member is now locked to drive-shaft 49 through the reel. Turning the control knob I4 clockwise (which knob always drives the reel directly through the pin-engaging slot in the drive shaft) will now serve to rotate the head through 180, until it is disposed directly upwardly, as seen in Fig. 19. At this end of the 180 travel, the por- Tube 6i has a V-shaped out in tion 3l of leg 29 abuts one edge of the arcute step-shoulder 23 in the cap It, and thereby prevents further clockwise rotation of the head member relative to the stanchion. Simultaneously, the wider spring lug 23 drops into and protrudes through the aperture 32 in the head member. This lug is suiiciently wide to engage cooperating lug 46 on the reel locking bar, and the lock moves about its pivot, forcing lug 45 out of engagement with the radial slot 43 in the reel. In this position of the parts, it Vwill be apparent that the reel is no longer locked to the head, and further turning of the control knob ciockwise turns only the reel, forcing the drive tape 52, and thereby the extensible antenna section l5 outwardly. The head is now held against any tendency to inadvertently return over its travel, by the action of the spring lugs, the lug 28 having sprung into aperture 32, while the lug 2'1 is snap-engaged with the depression 34 formed on the back of the head member.

When it is desired to return the antenna section i somewhat from the fully extended position, or to completely retract the antenna and re-align it with the windshield mullion, the control knob is turned in the counter-clockwise direction, When this return operation is initiated, the head member itself will not rotate until the upper section is completely retracted. This, as explained above, is due to the fact that the reel is unlocked and is free to turn relative to the head member, and the spring lugs 2'! and 28 are engaged respectively with the recess 34 and aperture 32 formed in the head member and hence resist any tendency of the head member to turn. However, as soon as the upper section is completely retracted, the small knob on top of the extensible section is brought into rm engagement with the top of the lower section. Since the tape can be wound in no further, continued counter-clockwise rotation of the control knob tends to rotate the head member and overcomes the pressure of the spring lugs 21 and 28. These are, accordingly, forced out of the recess 34 and aperture 32, permitting the lock bar 4| to again lock the reel to the head member, and the head returns over its 180 rotational travel, to its position of rest as shown in Fig. 1. In this position the antenna again springs into clip 6 and is held rmly.

In the event that the antenna is struck, which may occur when it is in elevated position, the head member 'I will merely bend rearwardly or forwardly, depending on whether it is struck from the front or the rear. The ears 65 on the end of tube 64 and their keyways 36, by which the head member 1 is secured, form a swivel joint which together with the slidability of tube 84 permits the head member to move rearwardly or forwardly. Fig. 5 illustrates one such movement, i. e. the forward movement of the head member. As will be seen from a comparison of Figs. 4 and 5, the head member will draw away from the slotted end 50 of the drive-shaft, carrying with it the tube B4 against the pressure of spring 6E. In this position, the head is free to move in any direction without harming the mechanism. With removal of the displacing force, the pull of the spring E6 transmitted through ears 65 to the keyways 3S in the head, will re-engage slot 50 and drive-pin 48 so that rotation of the knob I4 will move the antenna to any desired position.

From the foregoing description, it will be seen that the invention provides a novel antenna device embodying means responsive to rotary movement only of a control element to swing the antenna from its rest position to its operative position or vice versa, and means responsive to additional rotary movement of the control element for extending or retracting the antenna when in its operative position. Thus the device is very easy to operate and requires a minimum amount of elort on the part of the operator, and furthermore the device may -be operated by the driver of the vehicle without distracting his attention from the driving of the vehicle.

Further the swivel joint feature of thedevice safeguards it against injury by its being struck by objects, particularly when entering a garage. This is a very important feature in a device of this character which may extend a considerable distance above the vehicle roof, and is virtually certain to be struck at some time.

From the above description, it will also be apparent that the invention provides an antenna device which is highly compact, simple to install and operate, and has numerous advantages and desirable features. As an example of the compactness of the device, but not intended as a limitation, it might be pointed out that the device extends only about an inch beyond the outer roof line of the automobile. Further, in the present embodiment, the head diameter is in the neighborhood of one and one-quarter inches, while the steel tape drive permits the use of a base antenna section which, while it is only about five thirty-seconds of an inch in diameter, is capable of considerable extension.

The illustrated embodiment, and its particular positioning on an automobile body, are merely illustrative, and the invention contemplates such changes and modications as may fall within the scope of the appended claims.
